type FreeVarIdx = Int

data Sig varIx

The internal representation of a type. Function types are represented as a linked list with the init elems being the context followed by arguments of the function and the last being the result type.

Methods

show :: Sig varIx -> String

showList :: [Sig varIx] -> ShowS

sigsFromHie :: HieAST a -> Map Name [Sig FreeVarIdx]

Produce a Map from function Names to their type signature's internal representation.

sigFingerprint :: [Sig a] -> [Sig ()]

Used to produce an orderable key for matching up signatures that are likely to be equivalent. To allow for this, free vars must be homogenized which is what void does here.
